I have Lead Generation Landing Pages for people to register to download PDF files. Whenever someone registers, the landing page adds them to a contact list named specific for that PDF. I have an automation setup, so when an email is added to a PDF-specific contact list, it generates an email with the link to download the document. The URLs for the landing pages are in various places on my website. Recently, whenever I click on one of the landing page links, I get a browser error: This site can’t provide a secure connectionlp.constantcontactpages.com sent an invalid response. Try running Windows Network Diagnostics. ERR_SSL_PROTOCOL_ERROR It doesn’t matter if I click the link on my website or within the setup on Constant Contact’s website; I get the same error. After some troubleshooting, it turns out that my computers are the only ones getting this error – people not on my home network have no error; even my cellphone gets the error if it is on Wi-Fi, if I remove it from Wi-Fi, it works with no error. It seems obvious that something in my network is causing the error. I’ve tried several things: Rebooting the router Rebooting my switch (PCs are on ethernet) On 2 different PCs I tried Chrome and Firefox Clearing browser cache Disabling all extensions Incognito mode Deleting every Constant Contact-related cookie off the computer Verify system clock is accurate Clear SSL state Disabling Anti-virus and firewall (Norton 360) Verify Windows up to date Verified browsers up to date Not sure how to remedy this, any ideas?
